UNITED STATES PATENT orrica LOUIS LICHTHAN, 01' NEW YORK, N. Y., ASSIGNOB 1'0 CHBOKEPLATE, INQ, OF NEW YORK, N. Y., A COBPOBATIW OF NEW JERSEY HANGER FOR ARTICLES TO BE PLATED Application filed November 27, 1928. Serial No. 882,228.

This invention is an improvement in hangers for articles to be plated, and more particularly in a hanger for chromium platmg, enablin the articles to be supported in the most avorable-position for receiving the deposit. In electro-plating, the article is the oathode, and in order to obtain a maximum of efficiency, there must be a good electrical connection between the article and the hanger, from which the negative lead of the circuit extends.

In certain ware, pointed ends, as for instance, rollers havin trunnions, a firm grip of the article with e ficient electrical contact is difiicult to obtain. It is desirable in supportin articles of this character that the contact e at a plurality of oints well spaced from each other.

no of the primary objects of the present invention is the provision of a type of hanger, especially adapted for supporting were of the class above described, wherein the en aging element of the hanger is so arran e as to support the-article in substantial y horizontal position, contacting at a plurality of points, and resiliently pressed whereby to insure'good conduction.

Another object is the provision in such a hanger of means enga ing the trunnions of leave the exposed surface thereof free for the deposit of the metal.

Another object is the provision of a simple and inexpensive construction, adapted to support a maximum of articles in a minimum of space.

With'these and other objects in view the invention consists in the construction and novel combination of parts fully described hereinafter, illustrated in the accompanying drawin and pointed out in the claims appendedfiereto, 1t being understood that various changes in the form, proportion, size and minor details of construction within the scope of the claims, may be resorted to without departing from the spirit of the invention.

In the drawings forming a part hereof Fig. 1 is a transverse vertical section of 1 of the usual construction,

such as has reduced or- .present instance, is a roller,

a tank provided with the improved hanger.

Fig. 2 is a perspective view of a parties of the hanger.

The present embodiment of the invention is shown in connection with a plating tank having one or more cross bars 2 extending longitudinally or transversely of the tank, and adapted to support the rack forming the subject matter of the present invention.

he improved rack comprises a substantially U-sha'ped frame, composed of a body 3, and arms 4, each arm having a hanger 5 at its upper end to engage the cross bar. At suitable intervals cross bars 6 are connected with the sides of the frame in parallel relation, and parallel to the body 3 of the frame. These bars 6 are secured to the members 4 of the frame in any suitable manner, as for instance, by screws as shown, or by soldering or welding.

Each bar 6 is provided with a plurality of hangers, each of which is substantially yoke shaped, composed of a body 7 and arms- 8. The yoke is formed from wire of sultable gauge, and in the middle of .the body the wire is formed into an open ring 9, which fits the bar 6 loosely as shown in Fig. 2. The ring is secured to the bar in any suitable manner, in the present instance, by solder 1t), and each arm is provided'at its free end with an open ring 11, adapted to receive the ointed or reduced end of the article 12, whic in the having trunmons 13.

The arms of each yoke normall slightly toward their free ends, an to engage them with the trunnions, it is necessary to spring them outward awa from each other. When the roller is placed: the resiliency of the hanger forces the ends into close contact with the ends of thearticle, thus to provide a ood electrical contact. The bars 2, the frame, the cross bars, and the hangers, are all of conducting material.

What is claimed as new is 1. A hanger for articles ends, of substantially yoke shape and provided at the end of each armwith ano n ring, the rings of the arms being adapte to converge having reduced receive'the pointed ends of the article, the yoke being of resilient material and the arms normally convergin toward their free ends for the plurpose set orth.

U 2. A anger for articles having reduced ends, of su stantially yoke sha e and provided intermediate the ends of t e body, and at the end of each arm with an open ring, the ring of the body being adapted for connecm tion with 'a support, and the rings of the arms being adapte to receive the pointed ends of the article, the yoke bein of resilient material, and the arms norma 1y converging to- H ward their free ends for the purpose set forth- I d I 3. A hanger for articles having reduced ends, of substantially yoke shape and provided at the end of each armwith an open ring, the rings of the arms being adapted to receive 50 the pointed ends of the article, the yoke being of resilient material, and the arms normally converging toward their free ends for the pur ose set forth, and a su portin'gbar for the an er, to which the b y is secured.

4. A anger for articles having reduced ends, of substantially yoke sha e and provided intermediate the ends of t e body, and at the end of each arm with an '0 en ring, the ring of the body bein adapte for connection with a support, an the-rings of the arms being adapted to receive the pointed ends of the article, the yoke being of resilient material, and the arms normally-converging toward their free ends for the purpose set forth,

and a supporting bar over which the open ring of the body engages, said ring being se cured to the bar. a

5. A hanger for articles having reduced ends, ofsubstantially oke shape, and provided at. the end of eac arm with ahang'er for engaging the reduced end of the article,

the yoke bein of resilient material.
